inverse of f(x)=f(x)=ln(x-1)-ln(2x+1)

inverse

f (x) = f (x) = ln (x - 1) - ln (2 x + 1)

\frac{- 1 - e ^{x}}{2 e ^{x} - 1}

Solution steps

y = ln (x - 1) - ln (2 x + 1)

Replace

x

with

y

x = ln (y - 1) - ln (2 y + 1)

Solve for

y, x = ln (y - 1) - ln (2 y + 1)

\frac{- 1 - e ^{x}}{2 e ^{x} - 1}

+ cos (3 θ)

f (x) = x^{\frac{5}{7}} - 8

f (x) = 11 x + 12

f (x) = x^{\frac{5}{7}} - 4
